A heat pump can run but not cool due to low refrigerant charge, a failed run capacitor, an active or stuck defrost cycle, ice on the outdoor unit, or airflow/electrical issues. Older systems may simply need cleaning and servicing to restore performance. In Knoxville and nearby areas, our techs diagnose and fix these issues.
Quick checks:
- Clear ice or debris from the outdoor unit.
- If the system is older, schedule cleaning/service.
- Ask us to check refrigerant, capacitors, defrost, blower wheel, and high/low voltage wiring.
